The automatic material feeding device for the material caching comprises a conveying belt mechanism 1, a material distributing mechanism, a material arranging mechanism and a feeding mechanism; the conveying belt mechanism 1 is used for conveying and caching materials, and after a stack of supporting plate stacks is grabbed, the supporting plate stacks at the rear part continue to convey through the supporting plate stacks stacked above the conveying belt mechanism 1, so that the conveying belt mechanism 1 not only realizes the conveying function, but also plays a role in caching the materials; the material distribution mechanism is used for separating the supporting plate stacks continuously conveyed above the conveying belt mechanism 1; because the conveyer belt mechanism 1 is adopted to replace a stock bin, the pallet stack is lack of necessary limit, the pallet weight is lighter, the pallet stack is easy to misplace in the conveying process, the pallet stack is irregular, and the material grabbing failure and the material grabbing efficiency of the material grabbing robot are low; therefore, the material arranging mechanism is specially arranged for arranging the supporting plate stacks separated by the material distributing mechanism above the conveying belt mechanism 1, the supporting plate stacks are arranged and stacked neatly, and finally the stacked supporting plate stacks are fed to the material grabbing station through the feeding mechanism, so that the material grabbing robot can grab materials conveniently, and the production continuity is realized. Adopt conveyer belt mechanism 1 to carry out material transport and buffer memory, be fit for layer board materials such as the collet of not unidimensional model and top cap, cooperate feed mechanism, reason material mechanism and feed mechanism to accomplish the arrangement material loading to the layer board buttress simultaneously, guarantee the continuous transport of materials such as layer board, it is spacing to need not to set up the feed bin of different specifications and carries out the feed, has reduced equipment cost.

The automatic material buffer feeding device provided by the invention is described in more detail below with reference to the accompanying drawings and specific embodiments.

In a specific embodiment provided by the present invention, the automatic material feeding device for material caching comprises two parts, namely a bottom support conveying part and a top cover conveying part, wherein the bottom support conveying part and the top cover conveying part have the same size and structure, and the bottom support conveying part and the top cover conveying part have the same composition, and both comprise the conveying belt mechanism 1, a material distributing mechanism, a material arranging mechanism and a feeding mechanism. The bottom support conveying part and the top cover conveying part are arranged in parallel with each other by the conveying belt mechanism 1.

The conveying chain plates are arranged alternately and connected into a ring-shaped conveying belt, the conveying chain plates are arranged alternately and matched with the forked feeding supporting plate 5, and the gap between every two adjacent conveying chain plates is used for the fork heads of the feeding supporting plate 5 to extend into, so that the conveying chain plates are prevented from contacting with the conveying belt. For example, the conveying belt mechanism 1 adopts three parallel conveying chain plates arranged at intervals, the feeding supporting plate 5 is arranged in a double-fork shape, and two gaps between the three conveying chain plates are used for the double forks of the feeding supporting plate 5 to extend into the conveying chain plates to support the supporting plate stack. The material distributing mechanism comprises a tail end limiting cylinder 3, a tail end baffle 2 connected with the tail end limiting cylinder 3 and a material pressing cylinder 4 arranged above the tail end of the conveying belt mechanism 1, the tail end limiting cylinder 3 and the tail end limiting baffle are arranged towards the tail end of the conveying belt mechanism 1, the tail end limiting cylinder 3 is used for driving the tail end baffle 2 to move towards and away from the tail end of the conveying belt mechanism 1, and the tail end limiting cylinder 3 is arranged towards the conveying belt mechanism 1 and is the same as the extending direction of the conveying belt mechanism 1 in the setting direction or the stretching direction of the specific tail end limiting cylinder 3. The material pressing cylinder 4 is vertically arranged, when the material pressing cylinder 4 extends out, the top of the pallet stack on the conveying belt mechanism 1 is pressed, and meanwhile, the conveying belt mechanism 1 is paused. When the material pressing cylinder 4 contracts, the pressing of the supporting plate stack is removed, and the conveying belt mechanism 1 continues to step towards the limiting baffle plate to convey the supporting plate stack.

When the tail end limiting cylinder 3 extends out, the limiting baffle is driven to extend out relative to the conveying belt mechanism 1, the supporting plate stack above the conveying belt mechanism 1 is stopped and limited, the limiting baffle firstly contacts the first supporting plate stack at the tail end of the conveying belt mechanism 1, meanwhile, the material pressing cylinder 4 presses the second supporting plate stack at the tail end of the conveying belt mechanism 1, and the conveying belt mechanism 1 stops running. The first and second stacks are here in relation to the conveying direction of the limit stop and conveyor mechanism 1. The first stack refers to the end of the conveying direction of the conveying belt mechanism 1, namely the stack closest to the limit baffle, and the second stack refers to the stack adjacent to the first stack. When the first stack of supporting plate stacks are conveyed to the tail end of the conveying belt mechanism 1, the pressing air cylinder 4 presses the second stack of supporting plate stacks to prevent the second stack of supporting plate stacks from being conveyed continuously, and separation of the first stack of supporting plate stacks and the second stack of supporting plate stacks is achieved.

The material distribution mechanism also comprises a feeding supporting plate 5 for supporting the first stack of supporting plate stacks stopped by the limiting baffle and a compensation cylinder 6 for connecting the feeding supporting plate 5; the structure of the feeding supporting plate 5 can be arranged by referring to a fork of a forklift, and the feeding supporting plate 5 can shovel the first stack of supporting plates from the conveying belt mechanism 1 and support the first stack of supporting plates; the compensation cylinder 6 and the end limiting cylinder 3 are arranged in parallel, and the stroke of the compensation cylinder 6 is equal to that of the end limiting cylinder 3.

When the tail end limiting cylinder 3 extends out, the limiting baffle plate forms a stop for the first stack of supporting plate stacks, the compensation cylinder 6 is in an extending state, and the feeding supporting plate 5 shovels and supports the first stack of supporting plate stacks of the conveying belt mechanism 1; then the initial position is brought back to the shrink of terminal spacing cylinder 3, and at this moment, compensation cylinder 6 follows the shrink of terminal spacing cylinder 3, and because the stroke of compensation cylinder 6 and terminal spacing cylinder 3 equals, compensation cylinder 6 drives the shrink back of material loading layer board 5, and first buttress layer board buttress is transferred to first preset position and keeps with limit baffle's laminating, guarantees that terminal first buttress layer board buttress one side also is length direction's alignment. The first preset position is a material grabbing station of the material grabbing robot, so that the material grabbing robot can move to the material grabbing station to grab the supporting plates from the top to the bottom of the first stack of supporting plate stack one by one.

The material arranging mechanism comprises a limiting plate 7 arranged on the first side of the tail end of the conveying belt mechanism 1 and an arranging cylinder 8 arranged on the second side of the tail end of the conveying belt mechanism 1. Limiting plate 7 sets up in 1 terminal first side of conveyer belt mechanism and is the spacing that is also width direction for providing the opposite side for the layer board buttress, and limiting plate 7 can be spacing glass board or steel sheet, adopts the glass board usually, prevents to rust and pollutes the layer board, and the glass board is unlikely to shelter from the sight simultaneously, is convenient for observe the position of layer board buttress. The extending direction setting of the perpendicular conveyer belt of direction of stretching out and drawing back also of arrangement cylinder 8's direction of motion can be at the vertical push rod that extends of end connection of arrangement cylinder 8, and the length of push rod is not less than the height of layer board buttress, and the bottom of push rod is higher than 1 up end of conveyer belt mechanism and is less than a layer thickness with the interval between the 1 up end of conveyer belt mechanism. Drive the push rod through arrangement cylinder 8 and move towards conveyer belt mechanism 1, promote first buttress layer board buttress laminating limiting plate 7, realize first buttress layer board buttress width direction's alignment. In other words, the arrangement of the arranging cylinder 8 and the limiting plate 7 in the two sides of the first preset position is neat, the material grabbing robot can grab the supporting plate in the accurate positioning mode conveniently, the material grabbing failure is avoided, or the material grabbing is needed to be positioned at every time and then grabbed again, and the production efficiency is improved.

Further, reason material mechanism can also include with 8 parallel arrangement's of arrangement cylinder branch buttress spacing cylinder 9 and the locating part 10 of connecting branch buttress spacing cylinder 9, here locating part 10 specifically is the gag lever post, divide buttress spacing cylinder 9 and 8 parallel arrangement of arrangement cylinder also the two flexible direction the same, divide buttress spacing cylinder 9 to be used for when pressing material cylinder 4 to push down the second buttress palette buttress, drive the gag lever post and stretch into between first buttress palette buttress and the second buttress palette buttress, further separate first buttress palette buttress and second buttress palette buttress, make one side that first buttress palette buttress and second buttress palette buttress contact gag lever post also be the one side parallel and level of palette buttress length direction simultaneously. Through limit baffle, the alignment of layer board buttress each direction is realized to arrangement cylinder 8, limiting plate 7, branch buttress spacing cylinder 9 and gag lever post, is convenient for grab the material robot and snatchs the layer board in proper order.

The feeding mechanism comprises a feeding electric cylinder 11, wherein the feeding electric cylinder 11 is vertically arranged and connected with a feeding supporting plate 5 and a compensation air cylinder 6 and is used for driving the feeding supporting plate 5 and the compensation air cylinder 6 to move up and down. By setting the single ascending stepping amount of the feeding electric cylinder 11, the stepping amount of the feeding electric cylinder 11 is integral multiple of the thickness of the supporting plate. The grabbing robot can grab the supporting plate at the same height of the first preset position. Because the feeding supporting plate 5 is connected with the compensation cylinder 6, and if the feeding electric cylinder 11 needs to drive the feeding supporting plate 5 and the compensation cylinder 6 to integrally ascend in a stepping mode, the connection of the feeding electric cylinder 11 and the cylinder seat of the compensation cylinder 6 is only needed to be kept.

Further, the end of the conveying belt mechanism 1 is provided with an electric cylinder fixing frame 12, and the feeding electric cylinder 11 is vertically arranged on the electric cylinder fixing frame 12 and is arranged on one side of the electric cylinder fixing frame 12, which is opposite to the end of the conveying belt mechanism 1. One side at the top of electric cylinder mount 12 sets up pushes away material cylinder 13, pushes away material cylinder 13 and arranges cylinder 8 parallel arrangement in order, also sets up perpendicularly with the extending direction of conveyer belt mechanism 1 promptly, will be located the layer board to the second preset position of first buttress layer board top of first preset position through pushing away material cylinder 13. The second preset position is a second material grabbing station used for the material grabbing robot to grab the supporting plate, the second preset position is attached to the first preset position, and the distance between the second preset position and the first preset position is equal to the distance between the stroke of the material pushing cylinder 13 and the length of the supporting plate. In other words, the pushing cylinder 13 extends to push the supporting plate at the first preset position to the second preset position, so that the material grabbing robot can grab the supporting plate from the first preset position and the second preset position at the same time.

In order to improve the grabbing efficiency, the grabbing hand of the grabbing robot can grab two or even a plurality of parallel supporting plates at a single time, the supporting plates are arranged at a first preset position and a second preset position, the grabbing hand is convenient to match with the grabbing hand of the grabbing robot, and the grabbing efficiency is improved. For example, the pushing cylinder 13 moves the two-layer pallet on the top of the first stack of pallets in the first preset position to the second preset position by stretching each time, and the feeding cylinder 11 steps up by two thicknesses of pallets each time. After the pallet at the second preset position is grabbed, the pushing cylinder 13 moves again to supplement the pallet to the second preset position. After the pallets of the first stack pallet stack are grabbed, the feeding electric cylinder 11 descends, the compensation cylinder 6, the tail end limiting cylinder 3, the material pressing cylinder 4, the arranging cylinder 8, the stack separating limiting cylinder 9 and the like repeat the actions, the original second stack pallet stack is transferred and stacked to a first preset position, and the feeding electric cylinder 11 drives the second stack pallet stack to move upwards.

In the process of replacing the pallet stack, if a certain buffer material mechanism is not arranged, discontinuity of production is caused inevitably, and the production efficiency is reduced. Therefore, the invention also particularly arranges a buffer cylinder 14 and a buffer supporting plate 15 on the upper part of the electric cylinder fixing frame 12, when the supporting plate stack at the first preset position is about to be used up (if two layers of the first supporting plate stack are left, the buffer cylinder 14 can be flexibly arranged according to requirements) and the supporting plate stack needs to be replaced, the buffer supporting plate 15 is driven by the buffer cylinder 14 to extend out of the supporting plate bearing the rest of the first supporting plate stack, the feeding electric cylinder 11 returns, and the compensating cylinder 6, the tail end limiting cylinder 3, the material pressing cylinder 4, the arranging cylinder 8, the stacking limiting cylinder 9 and the like repeat the above actions to realize stack changing and material supplementing. The arrangement of the buffer air cylinder 14 and the buffer supporting plate 15 avoids the material supply from being cut off in the stack changing process, and ensures the production continuity.

The driving mechanism, the tail end limiting cylinder 3, the material pressing cylinder 4, the compensation cylinder 6, the feeding electric cylinder 11, the arranging cylinder 8, the stack separating limiting cylinder 9 and the material pushing cylinder 13 of the conveying belt mechanism 1 can be respectively provided with an independent control mechanism, coordinated movement among the cylinders or the electric cylinders is realized by setting time difference of two times of telescopic movement or lifting movement in the control mechanism, a control mechanism which is connected with and controls all the cylinders and the electric cylinders can be further arranged to control the coordinated movement of the electric cylinders and the air cylinders to finish the conveying of materials, and the control mechanism can be specifically set by referring to the prior art and adopting a computer or a single chip microcomputer. The control of the automatic material buffer feeding device can be finished by inputting the running time interval, the sequence and the like, so that continuous and automatic feeding is realized, and the production continuity is ensured.

All the electric cylinders or the air cylinders are used for driving a certain part to move with a certain stroke, and not only the air cylinders or the electric cylinders can be adopted, but also hydraulic rods or electric push rods can be adopted according to requirements, and the reciprocating motion of the corresponding stroke can be completed.
